Visible pipelines which contain a hazardous chemical product shall be labelled with the information needed to clearly identify the contents and risks associated with this as well as an arrow indicating the direction of flow.
Labelling shall be positioned close to the most dangerous points, such as valves and joints, and at appropriate intervalls. Pipelines with gas under pressure (over 200kPa) shall also be labelled as written above even though the gas itself is harmless.
Employer who fails to label pipelines according to §20 (first part) in the provision 2011:19 might be obligated to pay a sanction charge. Pipelines containing compressed air are excepted.
